Licht- und luftbeständiges Lithopon. Patentiert im Deutschen Reiche vom 18. September 1906 ab. Light and air resistant lithopone. Patented in the German Empire on September 18, 1906.
Versuche haben gezeigt, daß alle bis jetzt hergestellten Lithoponsorten sich im Sonnenlichte schwärzen, trotz Nachbehandlung mit den Superoxyden der Alkalien und Erdalkalien. Ein in Wasser oder Gummiarabikumlösung bereiteter und auf eine Glasplatte aufgetragener dünner Aufstrich von Lithopon, den direkten Sonnenstrahlen bei feuchter Atmosphäre einige Stunden ausgesetzt, liefert denTests have shown that all of the Lithopons produced up to now are exposed to sunlight blacken, despite after-treatment with the superoxides of the alkalis and alkaline earths. A thin spread of Lithopon prepared in water or gum arabic solution and applied to a glass plate, Exposed to direct sunlight for a few hours in a humid atmosphere delivers the
ίο besten Beweis. Nachdem man die Ursachen des Schwarzwerdens von Lithopon im Sonnenlichte in dem Vorhandensein von Zink- und Cadmiumion hauptsächlich in Form von Chloriden ZnCL2, CdCl2. erkannte, hat der Erfinder ein Verfahren ausgearbeitet, dieses Ion gegen das Sonnenlicht und die Atmosphäre unwirksam zu machen und somit unter Leinölfirnis ein vollkommen licht- und luftbeständiges Lithoponweiß herzustellen. Das vorliegende Verfahren besteht darin, daß man lichtunbeständiges Lithoponweiß mit einem Gemisch von leicht ihre Kohlensäure abgebenden kohlensauren Salzen und einem Chlor und Sauerstoff absorbierenden Salze behandelt. Am besten eignet sich ein Gemisch von Magnesiumcarbonat mit Alkalinitrit. Magnesiumcarbonat allein in irgendeiner Form angewendet liefert niemals ein lichtbeständiges Lithoponweiß dagegen ein' Alkalinitrit allein angewendet, ein solches von außerordentlich großer Lichtbeständigkeit. Die Behandlung mit Magnesiumcarbonat und Alkalinitrit liefert den erwähnten Effekt unerreichter Lichtbeständigkeit. Man kann diese Salze auf trockenem oder nassem Wege dem fertigen Lithopon hinzufügen. Mengen von je J/2 bis 5 Prozent, 40 ίο best proof. After the causes of the blackening of Lithopon in the sunlight in the presence of zinc and cadmium ions mainly in the form of chlorides ZnCL 2 , CdCl 2 . recognized, the inventor has worked out a process to make this ion ineffective against sunlight and the atmosphere and thus produce a completely light and air-resistant lithopon white under linseed oil varnish. The present process consists in treating non-light-resistant lithopon white with a mixture of carbonate salts which readily release their carbonic acid and a salt which absorbs chlorine and oxygen. A mixture of magnesium carbonate with alkali nitrite is best. Magnesium carbonate used alone in any form never produces a light-resistant lithopone white, whereas an alkali nitrite, when used alone, is one of extraordinarily great lightfastness. The treatment with magnesium carbonate and alkali nitrite provides the mentioned effect of unmatched light resistance. These salts can be added to the finished lithopone by dry or wet means. Quantities of J / 2 to 5 percent each, 40
auch weniger und mehr, Magnesiumcarbonat und eines Alkalinitrits genügen in der Regel. Die besten Resultate erzielt man auf folgende Weise:also less and more, magnesium carbonate and an alkali metal nitrite are usually sufficient. The best results can be achieved in the following way:
1. 100 Teile geglühtes und gemahlenes Lithoponweiß werden in Wasser mit je '/s bis 5 Teilen eines Alkalinitrits und Magnesiumcarbonate bei gewöhnlicher Lufttemperatur einige Zeit behandelt oder vermittels direkten Dampfes 1 bis 5 Stunden und mehr unter anhaltendem Bewegen der Flüssigkeit gekocht, alsdann filtriert und getrocknet, oder aber bei gewöhnlicher Lufttemperatur in wenig Wasser zu einem homogenen Teig angeknetet, getrocknet und gemahlen.1. 100 parts of calcined and milled Lithoponweiß are dissolved in water, each with '/ s to 5 parts of an alkali metal nitrite and magnesium at ordinary air temperature treated for some time or by means of direct steam from 1 to 5 hours and more cooked with continued movement of the liquid, then filtered and dried , or kneaded into a homogeneous dough in a little water at normal air temperature, dried and ground.
2. Man mischt auf einem Kollergange 100 Teile Lithopon, gewöhnliche Handelsware, mit je 1J2 bis 5 Teilen eines Alkalinitrits und Magnesiumcarbonat. Es lassen sich die Verfahren 1 und 2 auch der Reihenfolgenach mit Vorteil kombinieren.2. Mix on a swing Koller 100 parts lithopone, ordinary commercial products, each having 1 J 2 to 5 parts of an alkali metal nitrite and magnesium carbonate. Methods 1 and 2 can also be combined to advantage in sequence.
Es ist bekannt (vgl. britische Patentschrift 7819 vom Jahre 1906), lichtunbeständiges Lithopon ausschließlich mit den Neutralsalzen des Kaliums und Natriums zu behandeln, welche Zink aus seinen Salzlösungen auszufällen vermögen. Nach dem vorliegenden Verfahren aber wird Lithopon mit Alkalinitriten allein oder mit Zusätzen von Mischungen von Alkalinitrit und Magnesiumcarbonat bzw. Zinkcarbonat behandelt. Die angewendeten Alkalinitrite sind aber solche Neutralsalze, welche Zink aus seinen Salzlösungen nicht auszufällen vermögen, auch zeigen die Alkalinitrite ganz andere Wirkungen als diejenigen Neutralsalze, welche der in Frage stehenden briti-It is known (see British patent specification 7819 of 1906) that it is not light-resistant Lithopon can only be treated with the neutral salts of potassium and sodium, which Able to precipitate zinc from its salt solutions. According to the present proceedings but becomes lithopon with alkali nitrites alone or with the addition of mixtures of alkali nitrite and magnesium carbonate and zinc carbonate, respectively. The applied alkaline nitrites but these are neutral salts which zinc cannot precipitate from its salt solutions ability, the alkali nitrites also show quite different effects than those neutral salts, which of the British
sehen Patentschrift zugrunde gelegt sind. Die mitver;vvendeten Magnesium- bzw.. Zinkcarbonate .,.· sind/' bekanntlich nicht wasserlösliche Verbindungen, auch vermögen diese Zink aus seinen Salzlösungen ebenfalls nicht auszufällen. "Sie dienen lediglich als Mittel, die hygroskopischen Eigenschaften der Alkalinitrite abzuschwächen. see patent specification are based. The co-ver ; The magnesium or zinc carbonates used are known to be insoluble in water, and these are also unable to precipitate zinc from its salt solutions. "They only serve as a means to weaken the hygroscopic properties of the alkali nitrites.
